Add i128 support

Adds the following methods to the `ByteOrder` trait:

  * `read_{i128, u128}`
  * `write_{i128, u128}`
  * `{read_uint,read_int,write_uint,write_int}128`

Adds the following methods to the `ReadBytesExt` trait:

  * `read_{i128, u128}`
  * `{read_uint, read_int}128`

Adds the following methods to the `WriteBytesExt` trait:

  * `write_{i128, u128}`
  * `{write_uint, write_int}128`

And finally, add tests and benchmarks for i128 support.

Fixes #65
